.SH NAME
fas \- FAS SCSI Host Bus Adapter Driver
.SH SYNOPSIS
.LP
.nf
fas@\fIsbus-slot\fR,0x8800000
.fi

.SH DESCRIPTION
.sp
.LP
The \fBfas\fR Host Bus Adapter driver is a \fBSCSA\fR compliant nexus driver
that supports the Qlogic FAS366 \fBSCSI\fR chip.
.sp
.LP
The  \fBfas\fR driver supports the standard functions provided by the
\fBSCSA\fR interface. The driver supports tagged and untagged queuing, wide and
fast \fBSCSI,\fR almost unlimited transfer size (using a moving \fBDVMA\fR
window approach),  and auto request sense; but it does not support linked
commands.
.SS "Driver Configuration"
.sp
.LP
The  \fBfas\fR driver can be configured by defining properties in
\fBfas.conf\fR which override the global \fBSCSI\fR settings. Supported
properties are: \fBscsi-options\fR, \fBtarget<\fIn\fR>-scsi-options\fR,
\fBscsi-reset-delay\fR, \fBscsi-watchdog-tick\fR, \fBscsi-tag-age-limit\fR,
\fBscsi-initiator-id\fR.
.sp
.LP
\fBtarget<\fIn\fR>-scsi-options\fR overrides the  \fBscsi-options\fR property
value for \fBtarget<\fIn\fR>\fR. <\fIn\fR> can vary from decimal \fB0\fR to
\fB15\fR. The supported \fBscsi-options\fR are: \fBSCSI_OPTIONS_DR\fR,
\fBSCSI_OPTIONS_SYNC\fR, \fBSCSI_OPTIONS_TAG\fR, \fBSCSI_OPTIONS_FAST\fR, and
\fBSCSI_OPTIONS_WIDE\fR.
.sp
.LP
After periodic interval \fBscsi-watchdog-tick\fR, the \fBfas\fR driver searches
all current and disconnected commands for timeouts.
.sp
.LP
\fBscsi-tag-age-limit\fR is the number of times  that the \fBfas\fR driver
attempts to allocate a particular tag ID that is currently in use after going
through all tag IDs in a circular fashion.  After finding the same tag ID in
use \fBscsi-tag-age-limit\fR times, no more commands will be submitted to this
target until all outstanding commands complete or timeout.
.sp
.LP
Refer to \fBscsi_hba_attach\fR(9F) for details.
.SH EXAMPLES
.LP
\fBExample 1 \fRA sample of fas configuration file
.sp
.LP
Create a file called \fB/kernel/drv/fas.conf\fR and add this line:

.sp
.LP
\fBscsi-options=0x78;\fR

.sp
.LP
This disables tagged queuing, Fast \fBSCSI,\fR and Wide mode for all \fBfas\fR
instances. The following example disables an option for one specific \fBfas\fR
(refer to \fBdriver.conf\fR(5) for more details):

.sp
.in +2
.nf
 name="fas" parent="/iommu@f,e0000000/sbus@f,e0001000"
        reg=3,0x8800000,0x10,3,0x8810000,0x40
        target1-scsi-options=0x58
        scsi-options=0x178 scsi-initiator-id=6;
.fi
.in -2

.sp
.LP
Note that the default initiator ID in OBP is 7 and that the change to ID 6 will
occur at attach time.  It may be preferable to change the initiator ID in OBP.

.sp
.LP
The example above sets \fBscsi-options\fR for target 1 to \fB0x58\fR and all
other targets on this \fBSCSI\fR bus to \fB0x178\fR.

.sp
.LP
The physical pathname of the parent can be determined using the \fB/devices\fR
tree or following the link of the logical device name:

.sp
.in +2
.nf
 # ls \fB-l\fR /dev/rdsk/c1t3d0s0
 lrwxrwxrwx 1 root  other  78 Aug 28 16:05 /dev/rdsk/c1t3d0s0 ->

\&.\|.\|/.\|.\|/devices/iommu@f,e0000000\
     sbus@f,e0001000/SUNW,fas@3,8800000/sd@3,0:a,raw
.fi
.in -2

.sp
.LP
Determine the register property values using the output from  \fBprtconf\fR(8)
(with the \fB-v\fR option):

.sp
.in +2
.nf
SUNW,fas, instance #0
  \|.\|.\|.\|.
  Register Specifications:
      Bus Type=0x3, Address=0x8800000, Size=10
      Bus Type=0x3, Address=0x8810000, Size=40
.fi
.in -2

.sp
.LP
\fBscsi-options\fR can also be specified per device type using the device
inquiry string. All the devices with the same inquiry string will have the same
\fBscsi-options\fR set. This can be used to disable some  \fBscsi-options\fR on
all the devices of the same type.

.sp
.in +2
.nf
device-type-scsi-options-list=
    "TOSHIBA    XM5701TASUN12XCD", "cd-scsi-options";
cd-scsi-options = 0x0;
.fi
.in -2

.sp
.LP
The above entry in  \fB/kernel/drv/fas.conf\fR sets the  \fBscsi-options\fR for
all devices with inquiry  string \fBTOSHIBA XM5701TASUN12XCD\fR to
\fBcd-scsi-options\fR. To get the  inquiry string, run the \fBprobe-scsi\fR or
\fBprobe-scsi-all\fR command at the \fBok\fR prompt before booting the system.

.sp
.LP
To set  \fBscsi-options\fR more specifically per target:

.sp
.in +2
.nf
target1-scsi-options=0x78;
device-type-scsi-options-list =
    "SEAGATE ST32550W", "seagate-scsi-options" ;
seagate-scsi-options = 0x58;
scsi-options=0x3f8;
.fi
.in -2

.sp
.LP
The above sets \fBscsi-options\fR for target 1 to \fB0x78\fR and for all other
targets on this \fBSCSI\fR bus to \fB0x3f8\fR except for one specific disk type
which will have \fBscsi-options\fR set to \fB0x58\fR.

.sp
.LP
\fBscsi-options\fR specified per target ID have the highest precedence,
followed by \fBscsi-options\fR per device type. Global \fBfas scsi-options\fR
(effecting all instances) per bus have the lowest precedence.

.sp
.LP
The system needs to be rebooted before the specified \fBscsi-options\fR take
effect.

.SS "Driver Capabilities"
.sp
.LP
The target driver needs to set capabilities in the \fBfas\fR driver in order to
enable some driver features. The target driver can  query and modify these
capabilities:  \fBsynchronous\fR, \fBtagged-qing\fR, \fBwide-xfer\fR,
\fBauto-rqsense\fR, \fBqfull-retries\fR, \fBqfull-retry-interval\fR. All other
capabilities can only be queried.
.sp
.LP
By default, \fBtagged-qing\fR, \fBauto-rqsense\fR, and \fBwide-xfer\fR
capabilities are disabled, while \fBdisconnect\fR, \fBsynchronous\fR, and
\fBuntagged-qing\fR are enabled. These capabilities can only have binary values
(\fB0\fR or \fB1\fR). The default value for \fBqfull-retries\fR is \fB10\fR and
the default value for \fBqfull-retry-interval\fR is \fB100\fR. The
\fBqfull-retries\fR capability is a \fBuchar_t\fR (\fB0\fR to \fB255\fR) while
\fBqfull-retry-interval\fR is a \fBushort_t\fR (\fB0\fR to \fB65535\fR).
.sp
.LP
The target driver needs to enable  \fBtagged-qing\fR and \fBwide-xfer\fR
explicitly.  The \fBuntagged-qing\fR capability is always enabled and its value
cannot be modified, because \fBfas\fR can queue commands even when
\fBtagged-qing\fR is disabled.
.sp
.LP
Whenever there is a conflict between the value of \fBscsi-options\fR and a
capability, the value set in \fBscsi-options\fR prevails.  Only \fBwhom != 0\fR
is supported in the \fBscsi_ifsetcap\fR(9F) call.
.sp
.LP
Refer to \fBscsi_ifsetcap\fR(9F) and  \fBscsi_ifgetcap\fR(9F) for details.

rate in KB/sec. The  \fBtarget<n>-TQ\fR and the  \fBtarget<n>-wide\fR property
have value \fB1\fR to indicate that the corresponding capability is enabled, or
\fB0\fR to indicate that  the capability is disabled for that target. Refer to
\fBprtconf\fR(8) (verbose option) for viewing the \fBfas\fR properties.
